m concern that l, .llosEPrt E, Tmiriaix, county oi" Philadelphia andmsylvania, have invented certain lmproements in Renovatirh the followingis a spesi- `n *with pneiiinatii: cleaners.

- t the invention 1s to provide moratmg tool wherein a i5' j'etherethrough Will be nl( so that th 'ie parallel with iaixl; and yieilffons.

l in part he obereinatter more i the tira which shim' by way of l ,leembodiment of the invena 'View in siile elevation, ot

j my ii'njmwemeiits. Fig. View tllrourll the tool, the ing (ler yeshaving been ila; olf elearness in illusial View on the Connection, fftjie olf tool.

:ooi consists gen! a head Q. The' internal bore the renovating headproper is connected to the iate The slot 13, at the left as fie in il,is preferably made sli ger than the slot 13, at the right,

2./ Whith alos in assembling the brush or other Cleaning tool on thesupporting plate of the l Vwien the nuts are loosened, the plate o bemoved so as to bring the bolt 14, the bottom or inner end of the longSlot 13, which will release the plate at the other enti from thesecuring bolt 14.

The hei-.acl 2, is pro 'idetl with a laterally extending passage 1S, inorder to permit the chistlal'len air or other tluid to pass through thepassage with a minimum amount of resistance this to the friction againstthe 'Walls ot' their.. Ne through the head and shank of the tool. amaware that prior to my invention, swivel connections have been madeWhereinthe fastening bolt in the connecting of the parts passes directlythrough the passai the air, and said bolt obst-mots said tor .iowiti.the connecting means oona spring 1i., one end of which' is to conform tothe contour of the upentl ot the shank 1. l As clearly shown in l, andHI, the shank is formed with a recess 20, which provioes side Walls 21,against which the sides of the spring; 1S, are adapt-ed to abut, and thespring thereby held in proper position relative to the shank. Thisspring also at upper cnil abuis against a head or flange formed aroundthe upper end of the shank. The other eri/tl of the spring is cleliertmiin order to engage with a bearing 23, on the head il, which is formed inthe present instance by providing a boss or extension,

the outer face of which is suitably rounded vso orbeveled. This boss 'ispreferably positioned'in a line passing centrally through the passageconnecting the shank'and the head, and perpendicularly to the plane ofmovement of the parts.

The spring 19, is provided'with a hole 2i, through .which passes ascrew- 25, and said screw is secured in a boss or enlargement 26, formedin the shank l. A thumb nutA 27, engages the outer end of the screw andis adapted to bear on the spring in order to hold the spring in place.By ad-l justing the screw, the pressure of the lower end 'of the springvagainst the bearing 23, may be varied. It will be appai'ent that bythis construction, the head of the renovating tool may be swung aboutits swivel joint connection with the shank, and Awill be held in variousadjusted positions, through the friction between the parts vcaused bythe spring .pressing upon the bearing 23.

In the form o f my invention illustrated i in Fig. IV, the supportingplate is omitted and the renovating head 2 is formed with an internalbore QS. i The head is provided with' a flange 11a, which is tapered asat S- and adapted to receive a hose or other connection in a manner wellknown in this art.

Froml the above description, it will be apparent that I have provided aswivel connection for a i'enovating tool, which has a in combiliead at-:ind having a passage therethrough, a shank at-` tached to said head andhaif'ing a passage extending therethrough registering with the tached tosaid head and having a passage extending therethrough registering Withthe passage in said head, and means for atA taching said-shank to saidhead whereby said renovating member and head may be swung in a planeparallel with the longitudinal axis of said shank, said means includinga spring carried'by the shank and adaptedA to engage the head foryieldingly holding said shank and head in engagement with each other.

A renovating tool including in combination a renovating member,'a headrigidly attached thereto andhaving a'passage therethrough, said headhaving al bearing seat on one side face thereof and a' proiecting bearing boss on the other side thereof, a shank having a passage extendingtherethrough, 'i said shank having. a bearing face at one side thereofadapted to engage the bearing l face on the head, whereby the passagein' the shank will register with the passa-ge in said head, a bearingspring engaging said shank and adapted to be pressed against saidbearing boss for holding said shank and said head in engagement 'witheach other, a hthreaded bolt attached to said shank and extendingthroughsaid spring, and a nut vthreaded ofi` vsaid bolt and bearingagainst said-spring for farying the tension 95 of the spring on'ltliehvbeaiing boss.

In testimony whereof, I. have hereunto signed my name at Philadelphia,Pennsyl- Vaiiia, this third day of January 19112.
